Aug. 1, 1939. v A. H. MORSE 2,157,670

PIANO ACTION CONNECTION Filed June 17, 1956 FIG. 3

INVENTOR ARTHUR H. MORSE BY ATTOR N E Y Patented Aug. 1, 1939 UNITED STATES PATENT OFFICE PIANO ACTION CONNECTION Application June 17,

4 Claims.

This invention has reference to a new and novel way of making a connection between a piano key and the wippen of a piano action, in an upright piano where the scale is so short that part of the action is below the level of the keys.

Figure 1 is a side view of a piano action with key and connector.

Figure 2 is a front view of the wippen.

Figures 3 and 4 are details of ways of making the connector.

A keybed I supports a keyframe 2 on which are keys 3 mounted so as to move up and down at their rear ends. A piano action has, for each note, a wippen 4 carrying a jack 5. The jack 5 operates a butt 6 and a hammer 1 which strikes the string 8. On the rear of the key 3 is a rocker lever 9, adjustable by means of the screws I6, IT. A connector 10 operates in the longitudinal slot I l in the lower side of the wippen 4 and in an end slot in the rocker lever 9. In the connector 10 are pins 12 and I3 which operate respectively in the transverse slot l4 in the lower side of the wippen 4 and the transverse slot I5 in the upper side of the rocker lever 9.

Having thus described my invention what I claim is:

1. In a piano, a horizontally disposed, forwardly-rearwardly extending key provided with regulating means on a rear portion thereof, the said regulating means comprising a rocker arm on the upper surface of said key, the said rocker arm extending rearwardly beyond the rear end of said key and being provided in its overhanging portion with two slots, one of said slots being a transverse slot in the upper surface of said arm and the other of said slots being a vertical slot in the rear end of said arm, the said vertical slot extending forwardly to intersect the said transverse slot; an action including below said key a rearwardly-forwardly extending wippen provided in its lower surface with a transverse slot and a longitudinal slot, the said longitudinal slot intersecting the said transverse slot; and a link for connecting said key and said wippen comprising a bar having two substantially parallel pins, one near each end thereof, the said pins extending 1936, Serial No. 85,754

outwardly from said bar substantially at right angles thereto, one of said pins engaging said rocker arm in said transverse slot therein, the said bar passing through the vertical slot in said arm, and the second of said pins engaging said wippen in the said transverse slot therein, a portion of said bar immediate to said second pin being disposed within the said longitudinal slot in said wippen.

2. In a piano, a horizontally disposed, forwardly-rearwardly extending key provided with regulating means on a rear portion thereof, the said regulating means comprising a rocker arm on the upper surface of said key, the said rocker arm extending rearwardly beyond the rear end of said key; an action including below said key a rearwardly-forwardly extending wippen; and a link for connecting said key and said action, said link being pivotally connected to said wippen and to the overhanging portion of said rocker arm.

3. In a piano, a horizontally disposed, forwardly-rearwardly extending key provided with regulating means on a rear portion thereof, the said regulating means comprising an arm attached to said key and extending rearwardly beyond the rear end thereof and means for regulating the height of the rear end of said arm with respect to said key; an action including below said key a rearwardly-forwardly extending wippen; and a link for connecting said key and said wippen, pivotally connected to said wippen and to the overhanging portion of said arm.

4. In a piano, a horizontally disposed, forwardly-rearwardly extending key provided with regulating means on a rear portion thereof, the said regulating means comprising an arm attached to said key and extending rearwardly beyond the rear end thereof and means for regulating the height of the rear end of said arm with respect to said key; an action located at least partly below said key; and a link for connecting said key and said action, said link being pivotally connected to said action below said key and to the overhanging portion of said arm.
